Zusammenfassung
Calculates the Red-Edge Triangulated Vegetation Index (RTVICore) from a multiband raster object and returns a raster object with the index values.
Auswertung
Der Red-Edge Triangulated Vegetation Index (RTVICore) ist ein Vegetationsindex für die Schätzung von Blattflächenindex und Biomasse. Dieser Index verwendet Reflexion im NIR- und grünen Spektralband und an der roten Kante.
RTVICore = (100*(NIR - RedEdge) - 10*(NIR - Green))For information about other multiband raster indexes, see the Band Arithmetic raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
RTVICore (raster, {nir_band_id}, {redEdge_band_id}, {green_band_id})| Parameter | Erklärung | Datentyp |
raster | The input raster. | Raster |
nir_band_id | The band ID of the near-infrared band. The ID index uses one-based indexing. (Der Standardwert ist 7) | Integer |
redEdge_band_id | The band ID of the red-edge band. The band ID index uses one-based indexing. (Der Standardwert ist 6) | Integer |
green_band_id | The band ID of the green band. The ID index uses one-based indexing. (Der Standardwert ist 3) | Integer |
| Datentyp | Erklärung |
| Raster | The output raster with the RTVICore index values. |
Codebeispiel
Calculates the Red-Edge Triangulated Vegetation Index for a Sentinel-2 image.
import arcpy
RTVICore_raster = arcpy.ia.RTVICore("Sentinel2.tif",8,5,3)
